I have an arrayCollection with strings in them, is there some way I can databind a RadioButtonGroup to the array collection? As we can do for combo boxes [code]There is no RadioButtonGroup.dataprovider property.
View 2 RepliesI'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Script>

I have a small question. I am probably misunderstanding something, but when I do :

When the Flex SDK converts MXML to actionscript it generates a lot of databinding code. I don't want to bind a variable, for example if I know the variable will not change.
I can't seem to find a work around in Flex to disable the autogenerated databinding. Also, I was hoping this might also help with some of the runtime warnings thrown by databinding. To get around them, I sometimes use the following, which only throws syntax warnings (and don't appear in my console at runtime).
Syntax warning: Data binding will not be able to detect changes when using square bracket operator.
the new TextInput component which uses stagetext on 4.6 has this issue where if you bind a variable on it e.g
view1...
and i push a new view e.g view2, and pop it, hence reloading view1. on initial load, I can see that the textinput display the variable abruptly then the text vanishes afterwards..
I'd like to note that the variable is a stored data, and can be access on any view.
I have a problem with my AdvancedDataGrid which has inside it colums of radiobuttons.The problem is when I click on a cell in the Grid, the Radiobuttons selection become instable, some of the radio buttons of other colums become selected.The behavior I want is that when the selects the RadioButtons(the circle or its label), it become selected and not all the Cell in which the radioButton is.Here my code:
for (var idxStudio : int = 0; idxStudio < p_studios.length; idxStudio++) {
innerColumn = new AdvancedDataGridColumn();[code]....
The help page on the BindUtils.bindProperty function:url...Has this to say:"For example, to bind the property host.a.b.c, call the method as: bindProperty(host, ["a","b","c"], ...)." But what if I need to bind to host.a.b[2].c? How do I do that?
View 2 RepliesI need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change. I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

well, I have a combobox which I have bind his selectedItem property to a value object object, like this
<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />
the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this
[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}
my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,
I have creating a distributed note taking application in flex, it basically is a notepad I can keep in my desktop tray. When I add notes and goes back to a server and saves it in a database.
To am struggling to design the application correctly, I want to have a Syncing service that polls the webserver for changes and updates an Array of Note objects. The problem is that my note corresponds mxml component, aka SingleNote component. There are four different cases when being, a. a note is updated from the server poll, in that case I want to singlenote to update the settings b. a note is added to the array from the server, in that case a new SingleNote needs to be created c. a SingleNote is added from client, in that case a Note is added to array, and sent back to server d. a SingleNote is change from client, in that case the Note is updated in the array and sent back to server
The properties are SingleNote(Width, X, Y, Text).

I'm trying to set up a form that presents a combobox when an ArrayCollection it's bound to has several items, and doesn't present one when it's empty or only has one item. I've tried doing this by creating this class, but unfortunately, the data provider I've bound to is never not empty at the time the setter executes.
public class ComboboxOrFail extends ComboBox
{
public function ComboboxOrFail()

i'll have different number of columns in my dataGrid. DataGrid is privided from arrayCollection. I'm trying to add items to array collection using dynamic string 'x', like this:
for(i=0;i<time.length;i++) [code]........
At the end my 'result' array collection has to columns: 'name' with a value of 'name[i]' and 'session1' with a value o x string. I'm trying to increase nuber of 'session' columns in array collction, but it not working the way I planned.
Is there a way i can convert my array which is in the below format[code]...
Tricky part here is, i will not know how many values/lables user will enter, so it has to dynamically pick the array's.
When I tried to populate an arraycollection dynamically its saying no values found. Code that I used for this is given below:
[Bindable]
private var myARR:ArrayCollection=new ArrayCollection();
private function abc(){
var myStr:String="{year:'2004',Test1:10,Test2:20,Test3 :30}";
myArr.addItem(myStr);
}
I have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
Arraycollection:- [0] - name: abc
[1] - name: hello
[2] - name: hello1
[3] - name:hai
after filtering the arraycollection as 'hell' , the array collection is displaying like the below:
Arraycollection:-
[0] - name: hello1
[1] - name: hello
Can i know the reason why the index got changed after filter it?
* no server side code for filtering. it is only flex side filtering.

So far as it says above i have 10 questions setup i use a php script to submit answers to mysql and update the users score after checking the answer from mysql. The questions are all written out on a keyframe each with radio buttons and checkboxes depending on the question. Well anyway i will get to the point.
I have can test the quiz and can get to question 4 before i get undifiend from the radio buttons on that frame i dont know why i keep getting it it is setup the same as the first 3 questions with the same code but the radiogroup is named differently.This may be terrible code but it worked for the first 3 so i dont see why its not working for the rest of them :S

i'm trying to find a solution to this problem: in the frist frame of the project i have 3 radiobuttons (Mambasradio, Amaronradio, Mastajbuonradio). In the second frame i have a ComboBox (Centers). I created 4 Arrays (mambascenters, amaroncenters, mastajcenters, nothing) and i tried to change the Array of the Centers.dataProvider with the RadioButtons selections. So if i selected Mambasradio, the dataProvider will beCenters.dataProvider = new DataProvider(mambascenters)I tried a lot of things but i didn't figured out of this. It gives me a Null Object Reference error in second frame. Here's my code.
Frame1
import flash.text.TextField;

I am using RadioButtons within a radiobuttongroup. i want to change the order sequence of the radiobuttons of the group based on the end user's input.i have searched a lot, but all fell into vain.
I want to know whether it is possible to change the order of the radiobuttons?
I'm having a weird problem with my custom radio buttons. Here's what they look like in my fla file: I can't put images, so you will have to copy and paste these links : musique-chroniques.ch/1.jpg When I test them (CTRL + enter) they work fine. Once I put them online, they start acting strange on click: musique-chroniques.ch/2.jpg[/url] I thought maybe some actionscript could have interferred with them. I removed all the code from the animation to test it, but the problem remained.

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

the applicable differences between an ArrayCollection and a Vector in flex? I'm unsure if I should be using one over the other. I saw that Vector is type safe and that makes me feel better, but are there disadvantages?
public var ac:ArrayCollection = new ArrayCollection();
versus
public var vec:Vector.<String> = new Vector.<String>();
In my Main application I used label (like id=firstname) so we can use in main used firstname.text for databinding. But I have created canves custom component and load in main application using viewstack.In canves custom component how can I Bind label(id=firstname).I tried:var username:string = firstname.text but not show undefine firstname.How can I access all label and component in Main application to custom application.
View 1 RepliesI was wondering if it could be possible to create a databinding system in pure actionscript without using mx.binding.utils At least I would like to know what is the overhead of the databinding code and how exactly the ChangeWatcher knows when a property has been changed.
View 2 RepliesIn Flex, it's easy to convert the XML to Object and to ArrayCollection by using var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(); decoder.decodeXML( xml );
But is there a good way to convert ArrayCollection to XML.
I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,
